HAPPY makes all children's eyes light up. The cute superfit runner slipper is made for the first big steps of little adventurers. The warm felt provides a super soft feeling. The colourful, non-marking soles are made for all indoor adventures. The cute 3D animal motifs have an enchanting charm and are partly complemented by learning elements such as moving parts. The practical velcro fastener allows HAPPY to be opened wide. So the little adventurers can easily slip into the shoe and it can be individually adjusted.
